These observations document past conditions at a small and variable scale. They are not to be confused with an avalanche forecast. They come from a variety of sources. We can only vouch for the quality of those produced by the SAC forecasters and professional observers.

Snowpack Observation 		Far East Ridge of Tamarack Peak
Mount Rose Area 		Some skier triggered cracking on a small wind-loaded test slope Representative snow coverage in non-wind-loaded terrain. There were numerous exposed and barely covered rocks. Wind-loaded areas held more snow coverage, but the coverage decreased quickly below the ridges with many areas of bare ground still present. Numerous bushes, stumps, rocks, and other obstacles still exposed. Many areas of bare ground still remain due to a combination of wind-scouring and a lack of snow. Forecaster
